SUMMARY PROSPECTUS

November 28, 2022

Before you invest, you may want to review the Fund’s Prospectus, which contains more information about the Fund and its risks. The Fund’s Prospectus and Statement of Additional Information, both dated November 28, 2022, are incorporated by reference into this Summary Prospectus. You can obtain these documents and other information about the Fund online at www.mainmgtetfs.com. You can also obtain these documents at no cost by calling 1-866-383-9778 or by sending an email request to OrderMainMgtETFs@UltimusFundSolutions.com. Shares of the Fund are listed and traded on Cboe BZX Exchange, Inc. (the “Exchange”).

Investment Objective: The Fund seeks to outperform the MSCI All Country World ex-USA Index® (the “Index”) over a full market cycle while maintaining below-benchmark risk.

Fees and Expenses of the Fund: This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund (“Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Management Fees	0.55%
Distribution and Service (12b-1) Fees	0.00%
Other Expenses(1)	0.30%
Acquired Fund Fees and Expenses(2)	0.35%
Total Annual Fund Operating Expenses	1.20%
Fee Waiver and Reimbursement(2)(3)	(0.21)%
Total Annual Fund Operating Expenses After Fee Waiver	0.99%

(1) Estimated for the current fiscal year.

(2) Acquired Fund Fees and Expenses are the indirect costs of investing in other investment companies. The operating expenses in this fee table will not correlate to the expense ratio in the Fund’s financial highlights because the financial statements include only the direct operating expenses incurred by the Fund.

(3) The Fund’s adviser, Main Management ETF Advisors, LLC (the “Adviser”), has contractually agreed to reduce its fees and/or absorb expenses of the Fund, until at least February 28, 2024, to insure that total annual fund operating expenses after fee waiver and/or reimbursement (exclusive of any front-end or contingent deferred loads, taxes, brokerage fees and commissions, borrowing costs (such as interest and dividend expense on securities sold short), acquired fund fees and expenses, fees and expenses associated with investments in other collective investment vehicles or derivative instruments (including for example option and swap fees and expenses), or extraordinary expenses such as litigation (which may include indemnification of Fund officers and Trustees, contractual indemnification of Fund service providers (other than the Adviser))) will not exceed 0.64% of the Fund’s average daily net assets. These fee waivers and expense reimbursements are subject to possible recoupment from the Fund in future years (within the three years from the time the fees were waived or reimbursed), if, after such recoupment is taken into account, the expense ratio does not exceed the lesser of the expense limits in place at the time of the waiver or those in place at the time of recapture. This agreement may be terminated by the Board of Trustees only on 60 days’ written notice to the Adviser.

Example: This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example reflects the fee waiver and expense reimbursements for the duration of the waiver/reimbursement period only.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based upon these assumptions your costs would be:

1 Year	3 Years
$101	$360

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. The Fund has only recently commenced operations.

PRINCIPAL INVESTMENT STRATEGIES:

The Fund utilizes a “fund of funds” structure to invest in exchange traded funds (“ETFs”) that primarily provide exposure to non-U.S. equity securities of companies of any capitalization representing sectors and geographic regions that appear undervalued in comparison to their historical average price. The Adviser focuses its research on global macro-economic factors (relevant to the economy in general), micro-economic factors (relevant to individual companies) and fundamental factors (financial information that impacts the price or perceived value of a stock) to assess whether a sector or geographic region is expected to undergo a transformative change that could lead to near-term price appreciation of companies within that sector or region. Under normal circumstances, the Fund invests at least 50% of its total assets in funds that invest at least 50% of their respective total assets in securities of non-U.S. issuers organized or having their principal place of business outside the U.S.

The portfolio managers set price targets for each position and revisit a position when the price target is met, revising upwards when deemed appropriate or selling when the portfolio managers conclude the position no longer provides exposure to undervalued companies on the brink of a transformative change.

The Adviser rebalances the Fund’s portfolio when the portfolio managers deem appropriate. Given the longer-term nature of the Fund, an automatic monthly or quarterly rebalancing policy could be counterproductive to the Fund’s objective of seeking maximum return. From time to time, the Fund may use a covered call or covered put option strategy in an attempt to dampen volatility and generate additional returns.

The Fund is an actively managed ETF and does not seek to replicate the performance of a specified index. In selecting investments for the Fund’s portfolio, the Adviser adheres to the following investment process:

Assessing Market Conditions: The Adviser determines the Fund’s target allocations by identifying sectors (and their underlying industries and sub-industries) countries and regions it believes are poised for significant economic growth. To identify such sectors, countries and regions, the Adviser analyzes economic growth forecasts, changes in the factors driving growth, behavioral patterns among consumers, as well as other macroeconomic fundamentals over a 6- to 18-month horizon. The Adviser uses the Global Industry Classification Standard (“GICS”) in its sector analysis and may invest in country-specific sector funds. GICS sectors include: energy, materials, industrials, consumer discretionary, consumer staples, healthcare, financials, information technology, communication services, utilities and real estate.

Identifying the Appropriate ETFs: The Adviser then seeks to identify 5-20 index or actively managed ETFs to implement its strategic asset allocation by evaluating various factors in the respective ETFs including the respective underlying indexes they seek to track and portfolio holdings, sector exposure and weightings, liquidity profiles, and tracking error. At any given time, the Fund may have a significant percentage of its assets invested in one or more sectors or in one or more countries or geographic regions.

Option Strategy: The Fund pursues its objective by employing an option strategy of writing (selling) covered call or index based options on an amount from 0% to 100% of the value of the ETF shares in the Fund’s portfolio. The Fund seeks to earn income and gains both from dividends paid on the ETFs owned by the Fund and cash premiums received from writing or “selling”:

· covered call options or index based options on equity based ETFs held in the Fund’s portfolio and

· cash secured put options against cash balances in the Fund.

2

The Fund may not sell “naked” put or call options, i.e., equity options representing more shares of an ETF than the Fund has cash on hand and available to purchase or index options greater than the value of the underlying security.

Stock index options are put options and call options on various stock indices. The primary difference between stock options and index options occurs when index options are exercised. In the case of stock options, the underlying security, common stock, is delivered. However, upon the exercise of an index option, settlement does not occur by delivery of the securities comprising the index.

The option holder exercising the index option receives an amount of cash if the closing level of the stock index upon which the option is based is greater than, in the case of a call, or less than, in the case of a put, the exercise price of the option. This amount of cash is equal to the difference between the closing price of the stock index and the exercise price of the option expressed in dollars time a specified multiple.

A stock index fluctuates with changes in the market value of the stocks included in the index. A call option on a security is a contract that gives the holder of the option, in return for a premium, the right, but not the obligation, to buy from the writer of the option the security underlying the option at a specified exercise or “strike” price by or before the contract’s expiration. A put option on a security is a contract that gives the holder of the option, in return for a premium, the right to sell to the writer of the option the security underlying the option at a specified exercise or “strike” price. The writer of an option on a security has the obligation upon exercise of the option to purchase the underlying security at the exercise price. The Adviser’s option strategy typically targets one-month to three-month options. Options of any exercise price or maturity may be utilized.

Principal Investment Risks: As with all funds, there is the risk that you could lose money through your investment in the Fund. Many factors affect the Fund’s net asset value and price of shares and performance.

The following describes the risks the Fund bears directly or indirectly through investments in underlying ETFs. As with any ETF, there is no guarantee that the Fund will achieve its goal.

Allocation Risk: If the Fund’s strategy for allocating assets among different sectors and countries does not work as intended, the Fund may not achieve its objective or may underperform other funds with the same or similar investment strategy.

Authorized Participant Risk: Only an Authorized Participant that has entered into a contractual arrangement with the Fund’s distributor may engage in creation or redemption transactions directly with the Fund. The Fund’s distributor has entered into contracts with only a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem large blocks of shares known as “Creation Units,” Fund shares may be more likely to trade at a premium or discount to net asset value and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for ETFs that invest in non-U.S. securities or other securities or instruments that have lower trading volumes.

Covered Call Risk: The writer of a covered call option forgoes any profit from increases in the market value of the underlying security covering the call option above the sum of the premium and the strike price of the call but retains the risk of loss if the underlying security declines in value. The Fund has no control over the exercise of the option by the option holder and may lose the benefit from any capital appreciation on the underlying security.

Currency Risk: Investments in foreign currencies are subject to political and economic risks, civil conflicts and war and greater volatility. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates, imposition of currency controls and economic or political developments in the U.S. or abroad.

Derivatives Risk: The Fund’s use of options involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) the risk of mispricing or improper valuation; and (iii) the risk that changes in the value of an option may not correlate perfectly with the underlying asset, rate or index. Derivative prices may be highly volatile at times and may fluctuate substantially during a short period of time.

o Leverage and Volatility Risk: Derivative contracts ordinarily have leverage inherent in their terms. The low margin deposits normally required in trading derivatives, including futures contracts, permit a high degree of leverage. Accordingly, a relatively small price movement may result in an immediate and substantial loss to the Fund. The use of leveraged derivatives can amplify the effects of market volatility on the Fund’s share price.

3

o Options Risk: There are risks associated with the sale and purchase of call and put options. As a seller (writer)of a put option, the Fund will tend to lose money if the value of the underlying security falls below a specified price. As the seller (writer) of a call option, the Fund may experience lower returns if the value of the underlying security rises above a specified price.

o Put Option Risk: Options may be subject to volatile swings in price influenced by changes in the value of the underlying instrument. Although the Fund collects premiums on the options it writes, the Fund’s risk of loss if its options expire in-the-money (i.e., the Fund, as the seller of puts, owes the buyer of the puts) may outweigh the gains to the Fund from the receipt of such option premiums. The potential return to the Fund is limited to the amount of option premiums it receives; however, the Fund can potentially lose up to the entire strike price of each option it sells. The puts sold by the Fund may not perfectly correlate with the returns of their underlying stocks.

Emerging Markets Risk: Investing in emerging market nations involves not only the risks described below with respect to investing in foreign securities, but also other risks, including exposure to economic structures that are generally less diverse and mature, limited availability and reliability of information material to an investment decision, and exposure to political systems that can be expected to have less stability than those of developed countries. The typically small size of the markets of securities of issuers located in emerging markets and the possibility of a low or nonexistent volume of trading in those securities may also result in a lack of liquidity and in price volatility of those securities.

Exchange-Traded Fund Risk: The ETFs in which the Fund invests will not be able to replicate exactly the performance of the indices they track because the total return generated by the securities will be reduced by transaction costs incurred in adjusting the actual balance of the securities. This may result in a loss. Certain securities comprising the indices tracked by the ETFs may, from time to time, temporarily be unavailable, which may further impede the ETFs’ ability to track their applicable indices. ETFs in which the Fund invests are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. As a result, the cost of investing in the ETFs will be higher than the cost of investing directly in the ETFs underlying investments and may be higher than other mutual funds that invest directly in stocks and bonds. ETFs may also trade at a discount or premium to their net asset value.

ETF Structure Risk: The Fund is structured as an ETF and as a result is subject to the special risks, including:

·Not Individually Redeemable: Shares are not individually redeemable to retail investors and may be redeemed by the ETF only to Authorized Participants at NAV in large blocks known as “Creation Units.”. An Authorized Participant may incur brokerage costs purchasing enough Shares to constitute a Creation Unit.

·Trading Issues: An active trading market for the Shares may not be developed or maintained. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange. If the Shares are traded outside a collateralized settlement system, the number of financial institutions that can act as Authorized Participants that can post collateral on an agency basis is limited, which may limit the market for the Shares.

·Market Price Variance Risk: The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.

o In times of market stress, market makers may step away from their role market making in the Shares of ETFs and in executing trades, which can lead to differences between the market value of Shares and an ETF’s NAV.

o To the extent Authorized Participants exit the business or are unable to process creations or redemptions and no other Authorized Participant can step in to do so, there may be a significantly reduced trading market in the Shares, which can lead to differences between the market value of Shares and an ETF’s NAV.

o The market price for the Shares may deviate from an ETF’s NAV, particularly during times of market stress, with the result that investors may pay significantly more or significantly less for Shares than an ETF’s NAV, which is reflected in the bid and ask price for Shares or in the closing price.

o When all or a portion of an ETFs underlying securities trade in a market that is closed when the market for the Shares is open, there may be changes from the last quote of the closed market and the quote from an ETF’s domestic trading day, which could lead to differences between the market value of the Shares and an ETF’s NAV.

4

o In stressed market conditions, the market for the Shares may become less liquid in response to the deteriorating liquidity of an ETF’s portfolio. This adverse effect on the liquidity of the Shares may, in turn, lead to differences between the market value of the Shares and an ETF’s NAV.

Equity Risk: Equity securities are susceptible to general stock market fluctuations and to volatile increases and decreases in value. The equity securities held by the Fund may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors affecting securities markets generally, the equity securities of a particular sector, or a particular company.

Fluctuation of Net Asset Value Risk: The NAV of the Shares will generally fluctuate with changes in the market value of the Fund’s holdings. The market prices of the Shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of and demand for the shares on the Exchange. The Adviser cannot predict whether the Shares will trade below, at or above their NAV. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for the shares will be closely related to, but not identical to, the same forces influencing the prices of the Fund’s holdings trading individually or in the aggregate at any point in time. In addition, unlike conventional ETFs, the Fund is not an index fund. The Fund is actively managed and does not seek to replicate the performance of a specified index. Index based ETFs have generally traded at prices which closely correspond to NAV per share. Actively managed ETFs have a limited trading history and, therefore, there can be no assurance as to whether and/or the extent to which the Shares will trade at premiums or discounts to NAV.

Index Call Option Risk: Because the exercise of index options is settled in cash, sellers of index call options, such as the Fund, cannot provide in advance for their potential settlement obligations by acquiring and holding the underlying securities. The Fund bears a risk that the value of the securities held by the Fund will vary from the value of the index and relative to the written index call option positions. Accordingly, the Fund may incur losses on the index call options that it has sold that exceed gains on other securities in its portfolio. The value of index options written by the Fund, which will be priced daily, will be affected by changes in the value of and dividend rates of the underlying common stocks in the index, changes in the actual or perceived volatility of the stock market and the remaining time to the options’ expiration. The value of the index options also may be adversely affected if the market for the index options becomes less liquid or smaller.

Large Capitalization Company Risk: Large-capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large-capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

Limited History of Operations Risk: The Fund is a new exchange traded fund and has a limited history of operations for investors to evaluate.

Management Risk: The portfolio managers’ judgments about the attractiveness, value and potential appreciation of particular stocks or other securities in which the Fund invests may prove to be incorrect and there is no guarantee that the portfolio manager’s judgment will produce the desired results.

Market and Geopolitical Risk: The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate-change and climate-related events, pandemics, epidemics, terrorism, international conflicts, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on both the U.S. and global financial markets. The coronavirus (COVID-19) global pandemic and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, as well as the forced or voluntary closure of, or operational changes to, many retail and other businesses, had negative impacts, and in many cases severe negative impacts, on markets worldwide. It is not known how long such impacts, or any future impacts of other significant events described above, will or would last, but there could be a prolonged period of global economic slowdown, which may impact your Fund investment.

Sector Risk: The Fund may have significant exposure to a limited number of issuers conducting business in the same sector or group of sectors. Market conditions, interest rates, and economic, regulatory, or financial developments could significantly affect a single sector or a group of sectors, and the securities of companies in that sector or group of sectors could react similarly to these or other developments. If the Fund invests more heavily in a particular sector, the value of its shares may be especially sensitive to factors and economic risks that specifically affect that sector. As a result, the Fund’s share price may fluctuate more widely than the value of shares of a fund that invests in a broader range of sectors. Additionally, some sectors could be subject to greater government regulation than other sectors. Therefore, changes in regulatory policies for those sectors may have a material effect on the value of securities issued by companies in those sectors.

Performance: Because the Fund has only recently commenced investment operations, no performance information is presented for the Fund at this time. In the future, performance information will be presented in this section of this prospectus. Also, shareholder reports containing financial and performance information will be mailed to shareholders semi-annually. Updated performance information will be available at no cost by visiting www.mainmgtetfs.com or by calling 1-866-ETF-XPRT 1(866) 383-9778.

Investment Adviser: Main Management ETF Advisors, LLC (the “Adviser”)

Portfolio Managers: Kim D. Arthur, Chief Executive Officer of the Adviser, James W. Concidine, Chief Risk Officer of the Adviser, J. Richard Fredericks, Managing Director of the Adviser, and Alex Varner, Director of Research of the Adviser, are primarily responsible for the day-to-day management of the Fund and have served the Fund as its portfolio managers since it commenced operations in 2022. Each portfolio manager is involved in rebalancing the Fund’s portfolio.

Purchase and Sale of Fund Shares: Individual Shares may be purchased and sold in secondary market transactions through a broker dealer or at market price. Shares are listed for trading on the Exchange and trade at market prices rather than NAV. Shares may trade at a price that is greater than, at, or less than NAV. An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the second market (the “bid-ask spread”). Because the Fund has only recently commenced investment operations, no information on the Fund’s net asset value, market price, premiums and discounts and bid-asks spreads is presented at this time. In the future, this information will be presented in this section of the Prospectus and on the Fund’s website at www.mainmgtetfs.com.

Tax Information: Dividends and capital gain distributions you receive from the Fund, whether you reinvest your distributions in additional Fund shares or receive them in cash, are taxable to you at either ordinary income or capital gains tax rates unless you are investing through a tax-deferred plan such as an IRA or 401(k) plan. However, these dividend and capital gain distributions may be taxable upon their eventual withdrawal from tax-deferred plans.

Payments to Broker-Dealers and Other Financial Intermediaries: If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Adviser and its related companies may pay the intermediary for the sale of Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.
